Residual rotatory instability has been reported to occur after primary anterior cruciate ligament reconstruction (ACLR). Adding lateral extra-articular tenodesis (LET) improve patient outcome without the need for ACL revision in patients with residual rotatory instability after ACLR.

Residual rotatory instability has been reported to occur after primary anterior cruciate ligament reconstruction. The anterolateral ligament complex of the knee has gained attention for its role in rotational instability of the knee, especially in association with anterior cruciate ligament injuries.

Four patients presenting with residual rotatory instability after primary anterior cruciate ligament reconstruction without signs of graft failure underwent an isolated lateral extra-articular tenodesis with a modified Lemaire procedure. Pre- and postoperative outcome scores were assessed.

At a one-year follow-up, all patients reported functional knee stability. Pivot shift tests were negative and postoperative Lysholm scores were increased with a mean of 19.75 points. Tegner's scores equaled the pre-injury level.

An isolated secondary lateral extra-articular tenodesis procedure can be a valuable treatment option for moderate active patients with residual rotatory instability after a primary anterior cruciate ligament reconstruction without signs of graft failure.
